Reliable Data Transmission by using S-Boxes in Multi-Station Network by using Various Keys

The requirement of data security is an important parameter for all the industries and government for their survival in the world. Government requires the technique which provides the highest level of the security with minimum number of overheads; moreover the model does not allow the hacker to penetrate the security area, i.e. the number of attempts made by the hacker should be reduced, it can be done by reducing the time during transmission. The key must be generated from the data based on permutation.
